King Charles III is converting his two state Bentleys to run on biofuel as part of a broader sustainability initiative aimed at reducing carbon emissions and transitioning to electric vehicles in the future. This decision aligns with a series of environmentally friendly measures being implemented by the Royal Household, which also includes the installation of solar panels at Windsor Castle and repurposing gas lanterns at Buckingham Palace for improved energy efficiency. Sir Michael Stevens, Keeper of the Privy Purse, emphasized that these efforts are inspired by the King's long-standing commitment to environmental issues. The Royal Household's latest accounts reveal that the King is determined to make a significant impact on sustainability during his reign. Additionally, the Crown Estate has reported a financial boost from the green energy market, which will support royal funding in the coming years. This multifaceted approach reflects a growing recognition of the importance of eco-friendly practices within the monarchy.
